diffHunks.write::
	If true, diff-producing commands (`git diff`, `git log`,
	`git show`, or `git diff-tree` with a `--stat`, `--numstat`, or
	`--shortstat` format) write the hunks
	they compute to the diff-hunks store, filling it as a side effect.
	The `GIT_DIFF_HUNKS_WRITE` environment variable overrides this for
	a single invocation. Reading the store is controlled separately by
	`core.diffHunks`. See linkgit:git-diff-hunks[1]. Defaults to false.
